Correlations between δ138/134Ba and (a) (La/Sm)N, (b) 87Sr/86Sr, and (c) Ba/Th for the mid-ocean ridge basalt (MORB) and back-arc basin basalt (BABB) samples in our study and MORB samples analyzed by Nielsen et al.[7]. Data are from Table 1. Error bars represent 2SD uncertainties. The vertical dotted lines present the defined average (La/Sm)N[16], 87Sr/86Sr[28], and Ba/Th[28] of the depleted MORB mantle. Samples in the orange shade are marked as depleted MORB, and those in the blue shade are marked as normal-type MORB or enriched-type MORB.

δ138/134Ba versus (a) MgO, (b) SiO2 and (c) Na8 for MORBs and BABBs. Na8 = Na2O + 0.373 × MgO − 2.98 (from Ref. [27]). Data are from Table 1. The error bars represent the 2SD uncertainties.
